Abstract

We demonstrate that a [Co(bpy)₃]^2+/3+ (PF₆)_2/3 redox couple is an effective strategy for cost-effective and highly efficient dye-sensitized solar cells (DSSCs). Their high transmittance and large complex size make cobalt redox couples advantageous in back-illuminated devices. Furthermore, the use of thin TiO₂ films, together with the naturally formed blocking layer at the outermost surface of Ti substrate, effectively alleviate the drawbacks of cobalt electrolyte. By virtue of these simultaneous effects, we achieve a highly promising power conversion efficiency of 7.12%.
